SPECIFICATION forming part of Letters Patent No. 391,570, dated October23,1888.

Application filed May 11, 1888.

To aZZ whom it may concern.-

Be it known that I, DANIEL XVILDE, a citizen of the United States,residing at 'Washington, in the county ofVVashington and State of Iowa,have invented a new and useful Im provernent in Grain-MeasuringMachines, of which the following is a specification.

My invention relates to improvements in grain-measuring machines; and itconsists in the peculiar construction and combination of devices, thatwill be more fully set forth hereinafter, and particularly pointed outin the claims.

In the drawings, Figure 1 is a side elevation of a grain-measuringmachine embodying my improvements, showing the same attached to theelevator of a thrashing-machine. Fig. 2 is a similar view of theopposite side of the machine, the elevator being shown in section. Fig.3 is a front elevation of my improved grain-nieasuring machine. Fig. 4is a detail perspective view.

A represents the elevator of a thrashing-machine, which is provided withthe usual endless ohain of buckets, B, and has the downwardly-inclineddischarge-spout G at its upper end, into which the contents of theelevatingbuckets are discharged in succession. On the front side of theelevator, at a suitable distance from the upper end thereof, is arrangeda crossbar, D, the ends of which project beyond the sides of theelevator, and have their upper edges beveled on opposite sides, asshown.

. E represents a shaft, which has a notch on its under side, at asuitable distance from its outer end, engaging the upper edge of one ofthe projecting ends of the crossbar D, said shaft being therebysupported on the said crossbar. On the outer or front projecting portionof the shaft is journaled a measuringhead, F, the construction of whichis as follows:

G represents a pair of circular disks, which are connected at theircenters by a hub, H, that is journaled on the shaft E. The said diskshave their perimeters beveled or inclined inwardly toward each other,and are then provided with flanges I, which are arranged at asuitabledistance apart.

K represents radial partitioirplates, of which there are a suitablenumber, the said partition-plates extending from the hub to the cir-Serial No. 273,570. (Xo model.)

cumference of the measuring-head and con necting the disks G, andserving to divide the measuring-head into a number of measuringcompartments, L, oflike capacity.

M represents two pairs of diverging arms, which have their connectedinner ends keyed to the shaft E on opposite sides of the measuring-headand in proximity thereto. The outer ends of the said arms project beyondthat side of the measuring-head which is under the discharge-spout ofthe elevator, and are turned inward toward each other and provided withscrew-threads, as shown.

N represents a curved plate, which bears against the flanges I on oneside of the measuring-head, andhasits upper end bent outward at asuitable angle to form a support for a hopper, 0, that is securedthereto, the said hopper being arranged under the discharge-spout andover one of the compartments of the measuring-head. To the outer side ofthe curved plate N, near the upper and lower ends thereof, are securedtransverse clips P, the ends of which are bent outward at right anglesto form ears having openings to receive the threaded ends of the arms M.Clampingbolts R are screwed to the threaded portion of the arms and bearagainst opposite sides of the lugs or ears, and serve to secure thecurved plate rigidly to the arms,as will be readily understood. An arm,S, projects at right angles from the curved plate N, and has a notch onits under side at its inner end, which engages the bcveled upper edge ofone of the projecting ends of the crossbar D, the said arm therebyforming a pivoted support for the plate N, so that the latter is free toswing upward and downward with the shaft E, which carries themeasuring-head. The latter is provided on its outer side, at its beveledorinclinod ieriphery, with a series of laterally or obliquely arrangedcams, T, which correspond in number with the compartments of themeasuring-head, there being one of the said cams for each compartment ofthe measuring-head, and the said cams being arranged at regulardistances It will be observed that the offsets or shoulders at the rearends of the said cams are slightly in ad Vance of the partitionplates ofthe measuringhead. On the opposite side of the measuringhead at the oinositel inclined perimeter a. thereof, and aslight uistancein rear ol.each partition-plate, is a cam, U, of suitable size and shape.

On one side of the elevator, atasuitabledistance from the upper endthereof, is secured an inclined arm, V, to the outer end of whichisjournaled an anti-friction roller, W, thelatter being just above theupper side of the revoluble measu ring-head when the latter is in itselevated position.

X represents a curved arm, which is secured to the same side of theelevator box or trough at a suitable distance above the arm V, and hasits outer end bent downward and arranged in the paths of the cams T, forthe purpose to be hereinafter stated.

The free end of the shaft E passes through a vertical slot in aguide-plate, Y, that is secured to the rear side of the elevator box ortrough and projects beyond one side of the same, and on the said freeend of the said shaft is arranged a weight, Z, which is adapted to bemoved inward and outward on the shaft, so as to counterbalance themeasuring -head, and thereby normally keep the same in its elevatedposition. The said weight Z has a set-screw, A, which is adapted toimpinge on the shaft E, and by means of which the weight may be securedat any desired adjustment on the shaft. Rigidly secured to the shaft Eat a suitable point is a circular disk, B, which is provided in itsouter side with a notch or shoulder, O.

D represents a ratchet -wheel, which is journaled on the shaft E, bearsagainst one side of the disk B, and has the peripheral ratchet-teethnumbered from 0 to 9 and representing units of measurement-say bushels.On the opposite side of the disk B is arranged a ratchet-wheel, E, whichis also journaled on the shaft E, which is likewise provided withperipheral ratchet-teeth numbered from 0 to 9 consecutively andrepresenting tens. The diameter of the ratchet-wheel D and E and of thedisk B is equal.

F represents a coiled extensile spring,whioh is arranged on the shaft E,has its outer end bearingagainst a cross-pin or stop on the shaft,and'has'its inner end bearing against the center of the wheel E, thefunction of the said spring being to keep the wheel E normally incontact with the disk B.

G represents a spring-pawl, which is attached to the inner side of thewheel D and has the tappet-arm at its free end,which bears against theperiphery of the disk B and pro- 5 5 jects across the periphery of thewheel E.

H represents a spring-arm or detent,which is secured to one side of theelevating-trough or box and has its free end engaging the ratchet WheelD.

The operation of my invention is as follows: The machine is in itsinitial position, when the revoluble measuring-head is elevated and thewheels D and E are so turned that the figures 0 thereon are oppositeeach other. As the material in the elevating buckets reaches the upperend of the elevator,it is discharged through the spout into the hopperso as to sustain the weight of the revoluble head and of the contents ofone of the measuring-compartment until said contents reach a certainunit of measure-say one bushel. As soon as this amount ofgrain isdischarged into the revoluble head the latter is caused to descendslightly and to incline the shaft E so as to disengage the cam U,previously in contact with the stop-roller W, from the latter, andthereby enable the revoluble head to be partly rotated by the weight ofthe material in one of its compartments until the said compart' ment hasmoved entirely from under the plate N, thereby causing the lower side ofthe said compartment to be opened and the contents thereof to bedischarged into a suitable receptacle or receiving sack or vessel. (Notshown.) As the measuring-head descends, the shaft E, by being inclined,raises the ratchet-wheel D, so as to cause the same to move from underthe free end of the spring arm or detent H, thereby causing the latterto slip over the said ratchet-wheel and take a fresh hold on atoothbelow the one with which it previously engaged, as will be readilyunderstood. As the revoluble head becomes lowered, as before stated,bythe prepondering weight of grain, so as to cause one of the stops orcams U to disengage the roller \V, the said revolublehead rotates anddischarges the accumulated grain therein, as before described, and whilethe revoluble head is thus partly rotated and its contents are beingdischarged the outer side of one of its cams T comes. in contact withthe inner side of the outer end of arm X, so as to raise the revolublehead to its former position and assist the counterbalancingweight, andthus lower the rear end of the shaft E to its initial position, and bythe descent of the said shaft cause the spring-arm H, by engaging a newtooth on the ratchet-wheel D, to turn the-said wheel D, so as to causethe figure 1 thereon to be ranged opposite the figure 0 on the wheel ordisk E, and thereby indicate that one bushel of grain has been measuredby the machine. At each subsequent similar operation of the measuring-machine the wheel D is moved a corresponding distance until thesame has made a complete revolution,when its pawl G will enter therecess in the disk B, and thereby become engaged with one of the teethof the wheel or disk E, so as to move the latter forward one space onthe eleventh operation of the machine, and thereby indicate that elevenbushels of grain have been measured, the figures on the wheels D and Ebeing respectively 1 and 10, equal eleven, and so on, as far as thecapacity of the machine will admit.

A grain-measuring machine thus constructed is especially adapted formeasuring the grain discharged from a thrashing machine, but may beemployed with equally good-results for other purposes.

Having thus described my invention, I claim-- 1. The combination of thecounterbalance shaft or arm E, the revoluble head journaled thereon andhaving the side plates or disks and the radial partitionplates, and thecurved plate N, covering one of the open sides of the revoluble head andconnected to the counterbalance-shaft by suitable supports, for thepurpose set forth, substantially as described.

2. The combination of the counterbalanced shaft, the revolublemeasuring-head journaled thereon having the compartments and providedwith the ears or stops U, and the roller or stop W, adapted tosuccessively engage the said ears or stops U as the head partlyrot-ates, substantially as described.

3. The combination of the counterbalanced shaft E, the revolublemeasuringhead journaled thereon having the peripheral stops or ears U onone side and the oblique cams T on the opposite side, the stop V, toengage each of the stops U in succession as the revoluble head rises,and the arm X, adapted to be engaged successively by the cams T, so asto ele vate the revoluble head as the latter rotates, substantially asdescribed.

4. The combination of the counterbalanced shaft, the revoluble headjournaled thereon, the stops, substantially as set forth, to control thepartial rotations of said head, the registering disks or Wheels on thecounterbalancing-shaft revoluble thereon and movable verticallytherewith, and the arm H, secured to a fixed support and engaging saidregisteringwheels, substantially as described.

5. The combination, in a grain-measuring machine,of the counterbalancedshaft, the revoluble head journaled thereon, stops, substantially as setforth, to control the partial rotation ofsaid revoluble head, the diskB", rigidly secured to the shaft and having the notch in one side, thenumbered registering ratchet- Wheels D and E, journaled to the shaft andarranged in contact with the disk B, the pawl G, secured to wheel D andadapted to engage Wheel E, substantially as set forth, and the arm H,secured to a fixed support and engaging the wheel D, substantially asdescribed.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
